I'm curious about one little detail on the accelerated Minimig.

What speed-grade is the 68k used in the video?  It seems that the 16MHz part is the most easily available from Digikey, and that's what I got.  I'd be surprised to see it going all the way up to 28MHz!

Also, what 68k grade do the amigakit Minimigs ship with?

I hope this is not too late for inclusion in the LPC2388 version...

Since this ARM controller has a dedicated RTC module on chip, I'd like to suggest placing a CR2032 lithium battery with holder on the piggyback module/new PCB.  This is the type used on PC motherboards and generally known to be leak free.

I don't know what it involves in terms of software/FPGA coding, but it would be a nice touch having files with correct time stamps.  Always if the Amiga OS is Y2k compliant, anyway.
